Do not trades until they get rid of these short rules. It is screwing up the pricing. I spoke with a friend this weekend who works for proshares and he said that the skf and uyg I believe are based off a swap that they can't price. All I know is that since friday am these things have been severely mispriced.

SKF is definitely broken. This morning I thought I was looking at the wrong symbol. Here are one minute bars of the first hour with SKF on the left and XLF on the right.

I trade SKF nearly 5-10 times a week and today seeing it trade the way it is, is really pissing me off, I know it isnt suppose to be trading like this but is due to the damn ban on shorting, SKF is really out of whack, this ETF should be trading well above $105 right now yet its trading down with the entire index, thats great, you see how everything is F$%KED UP since they came in and tried to prop the markets up. This market is totally different from what it was just 48 hours ago. They should just halt it for the time being, not fair to the individual investor who is playing the right side of the trade but not benefiting from the downfall in the sector today.
